The purpose of this study was to evaluate the influence of different beef cuts on their potential for adding value by assessing processing characteristics, composition, shelf-life, and sensory attributes of these cuts as beef bacon. Six briskets (Institutional Meat Purchase Specification [IMPS]#120), 6 clod hearts (IMPS#114E; divided horizontally into 2 halves: silver-skin side and non–silver-skin side), 6 flanks (IMPS#193), 6 outside flats (IMPS#171B), and 7 short plates (IMPS#121A; cut into a deboned short-rib half and navel half) were sourced commercially from separate Canadian quality grade AA beef carcasses. Data for processing yields, composition, and image analysis were analyzed as a generalized linear mixed model with fixed effect of cut and random effect of replication nested within block (processing group). Sensory data collected using a trained sensory panel were analyzed in the same manner, with an additional fixed effect of storage day and additional random effects of session and panelist. Rested pump uptake, which was targeted at 20%, was not different (P = 0.21) among cuts; however, smokehouse cook yield differed (P < 0.01) among cuts, with heavier cuts (brisket, plate cuts, and outside flat) generally having greater yields compared with lighter cuts (clod cuts and flank). As expected, composition of bacon slices was affected (P < 0.01) by cut, with leaner cuts (clod cuts, flank, and outside flat) having greater moisture, lower lipid levels, and greater protein compared with fatter cuts (brisket and plate cuts). Sensory analysis revealed significant differences in muscle fiber toughness and connective tissue among cuts. The differences that were quantified in this study should allow manufacturers to tailor their cut selection to the processing specifications that may be most profitable and well-suited for the meat industry and its customer base. Overall, this research should help define beef bacon and further indicate that a variety of beef cuts can be used to manufacture beef bacon.
